Advances in membrane-based oil/water separation
Oil is a widespread pollutant from oil spills to industrial oily wastewater in the oil and gas, metalworking, textile and paper, food processing, cosmetics, and pharmaceutical industries. A wastewater of particular concern is produced water, an oily waste stream from hydrocarbon extraction …

Fabrication and characterization of nano-engineered membranes for oil-water separation
… is the design and testing of membranes for separation of water-in- oil (w/o) emulsions. A polycarbonate membrane treated with octadecyltrichlorosilane (OTS) is used to filter a 3 wt% w/o emulsion. The permeate is characterized to have no measurable water content by microscopy, dynamic light …

Nature-inspired systems exploiting porous media for multiphase flows
… (1) How multilayered feathers enhance underwater superhydrophobicity. Inspired by ducks, here we demonstrate that air pockets can withstand up to five times more hydrostatic pressure when using stacked layers of synthetic feathers instead of a single layer. The mechanism for the …

Optimization of hydrophobic meshes for oil spill recovery
… oleophilic surfaces. These meshes can perform oil/water separation in situ, continuously, via capillary action. The goal of this study is to determine the potential of hydrophobic meshes as oil spill recovery devices. A fabrication method was developed using steel mesh dip-coated in a hot …

Field Trials of Ex Situ Smouldering Treatment (STARx) of Oil Sludge
… Here STARx is evaluated for the first time in soil pile configurations, using an engineered base concept called HottpadTM, at both the prototype (0.35 – 1.3m3) and field (80 – 160m3) scales. The treatment was applied to oily sludge from crude oil tank bottoms and oil water separation processes …

Examination of produced water from the Al-Hamada oilfield, Libya.
Produced water is generated to the surface from oil production. Because of the complex composition of produced water (a mixture of different organic and inorganic compounds and residues of oilfield chemicals - added to aid oil water separation) and due to the outcome of increasing volume and effect …

Fundamental study of hydrophobic microporous membrane contactors for the recovery of insoluble oil from oil-water mixtures
Insoluble oil and water mixtures occur in many industries such as food, metallurgical, or biofuel production. In particular, as we strive to meet global energy demands, the associated risks and waste management of the oil and gas industry must be addressed. Technologies capable of separating oil …

Analytical design method for cold production of heavy oil with bottom water using Bilateral Sink Wells
Few heavy oil reservoirs with strong bottom water drives have been developed successfully because of severe water coning. Water coning tends to cause low ultimate recovery, low well productivity, and high water production. Although thermal and gravity-assisted methods might improve recovery in oil …

Scalable Synthetic Trees for Transpiration-Powered Hydraulic Systems
… trees utilize hydraulic mechanisms to draw water from the soil, through their roots, and up to their leaves, sustaining hydration through transpiration. This process is reliant on the difference in relative humidity between the leaf and the ambient to promote evaporation, and synthetic trees …
